Cubic Feet per Second (ft³/s) to Gallons per Minute (GPM) Flow Unit Conversion Calculator

The online conversion tool allows users to convert ft³/s measurement into the commonly used unit GPM for water treatment and plumbing and industrial fluid management systems. Designers use this conversion when creating water distribution networks together with fluid flow optimization processes for establishing effective hydraulic operations.

Definition: Cubic Foot per Second (ft³/s) 

The US customary and imperial measurement systems use the unit Cubic Foot per Second (ft³/s) for measuring volumetric flow rate. The unit describes fluid volume which reaches a specified point each second. Cubic Foot per Second serves as a primary measurement tool for hydrological observations as well as river flow investigations along with extensive water distribution strategies.

Key Applications of Cubic Foot per Second (ft³/s)

• The measurement of stream and river flow rates occurs through procedures.
• Engineers use flood control system and drainage network design as key applications.
• Water flow rates used for measuring municipal water supply systems as well as irrigation systems.

Definition: Gallon per Minute (GPM) 

The GPM unit stands as one of the dominant standards for measuring fluid flow rates throughout the United States in plumbing operations and fire protection infrastructure and industrial fluid control systems. A specific point measures fluid passage by counting the number of US gallons each minute. One cubic foot equals 7.48052 US gallons.

Key Applications of Gallons per Minute (GPM)

• Household and industrial water distribution systems.
• Fire suppression and sprinkler system design.
• The operation of water treatment facilities falls under similar categories as cooling system management.

Formula for ft³/s to GPM Conversion

The conversion of measurements between Cubic Feet per Second (ft³/s) and Gallons per Minute (GPM) happens through applying this equation:

Flow in GPM = Flow in ft³/s × 448.831

Flow measurement in GPM equals the value of ft³ in at a rate of 448.831.

By multiplying flow rate in ft³/s with the conversion factor 448.831 you can obtain equivalent GPM results.

Example Calculation 

Suppose you have a flow rate of 2 ft³/s. 

To convert it to GPM: 

2 × 448.831 = 897.662 GPM 

So, 2 ft³/s is approximately 897.66 GPM (rounded to two decimal places).
